Printing out the config value used in the pass:

```
The value seems to always be the same no matter what you specify in the options:
```
$ echo | mlir-opt --canonicalize
canonicalizer config.useTopDownTraveral = 1
module {
}
$ echo | mlir-opt --canonicalize='top-down=false'
canonicalizer config.useTopDownTraveral = 1
module {
}
$ echo | mlir-opt --canonicalize='top-down=true'
canonicalizer config.useTopDownTraveral = 1
module {
}
```
